IMPROVEMENT IN LAMP-CHIMNEY FASTENINGS.

TO ALL WHOM IT MAY- CONCERN:

Be it known that we, JOHN ALLEN and CHARLES E. F. LEWIS, of the city ofWashington, and Distrietof Columbia, have invented an Improved Holderfor Chimneys for Lamps and Globes, and-we do hereby declare thefollowing to be an exact description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,making a part of this specification, in which Figure 1 is a perspectiveview, and

Figure 2 a sectional view of the holder.

The nature of our invention consists in a circular and grooved holder,to receive the flanged base of a glass chimney, the holder being dividedinto segments, andopcrating on one or more hinges, and fastened by aclasp or catch; and the object is to prevent the chimneys from beingbroken or rattling loosely, -as usual, and moreteasily and firmlyinserted in the top of the burner. v

A representsthe glass chimney; B, the ordinary brass burner, with itscommon cone C; D, the ordinary thumb-ratchet for raising or lowering thewick in the tube G is the circular grooved and adjustable holder,divided into two or more segments of a circle, that are grooved in theinside for the flange of the base of the chimney to fit in. One halfcircle, H, of the holder G, is made fast to the upper rim of the burnerB, upon which the cone 0 rests, while the other half circle, G, ishinged K to the end of H,- and swings horizontally to the burner B, andwhen closed completes the circle and clasps the flange of the base ofthe chimney, holding it in the groove L; and the circular segments arefastened together by means of a screw, spring, or other device, toanswer as a catch, M. A hinge, N, allows theholder to be opened upwardand outward. These segments or groove-holders may be divided to openeither horizontally or upward, and held by hinges, springs, or any kindof suitable fastening-s, and in the groove L we insert a ring of rubberor soft elastic material, that the flange of thebase of the chimney maybe held securely yet safelytrom the effects of the expansion by heat.

What we claim as our invention, and desire to secure by Letters Patent,is

1. The circular and grooved holder, divided into segment-s, operating onhinges, and held by i'asteni'ngs,

as herein described and forthe purposes set forth.

2. We also claim the use of an elasticor rubber ring, fitted into thegroove of the holder, for the purpose set forth.
